Effects of heat and mass transfer on nonlinear MHD boundary layer flow over a vertical surface with variable stream functions

The problem concerning with a nonlinear laminar boundary layer, heat and mass transfer flow of an incompressible, viscous and electrically conducting fluid past a continuously moving infinite vertical porous plate under the influence of a uniform magnetic field is considered. Consideration is given to heat source and thermal diffusion. A similarity transformation has been utilized to convert the nonlinear partial differential equations into nonlinear ordinary differential equations. The numerical solution of the problem is obtained using the Runge Kutta Gill method. Velocity, temperature and concentration fields are shown graphically to study the effects of parameters entering into the problem. Analysis of the results shows that the flow field is influenced appreciably by the presence of suction at the surface, chemical reaction and magnetic effects.
